To all whom it may concern:

I Be it. known that I, THOMAsH'ENRY GnAsse 00E, a subject of the King ofGreat Britain and Ireland, residing at Ivydale;Herongate 5 Road,Wanstead', in the county of Essex,

' England, have invented certain new and usereted-Air Apparatus, ofwhich the following 'apparatusforproducing carbureted air.

Fi 1 2 is a planview ofthe apparatus shown in ig.'11. I, .1 Incarryingmanner arrange-to'putvarious sections of a carbureter successively andautomatically intoor outofi operation, accordingjtothe do? .mand. Thecarbureter consists inxone-formfl of a shallow circular chamber a,closed atatha rd 5 I top band provided withsuitable means for heatingit'fls, .for instance a j acket p' of hot I gases, 'hots water, or'swarm-these heating means bein preferably under-controhas is hereinafterdescribed.

, The inventionfiuther consists in"'providing' 6o Thecarburetenisdivided by partitions d into three sections x, w, and x, 1;, Itsmteriorprovide'openings f, f, and f communicat ing with boxes or chests g, gf,and 9 into which the air-supply may be delivered through pipes h, h, andk from/a suitable pump or blower. ;.I

On the opposite side of the carbureter .I

rovide similar enin s j, and and P P o 7 7 boxes 7c, is, and k for thecarbureter air-outlet, these boxes being preferably connected togetherand provided with a common'foutlet-pipe g, leading to a receptaclecapable of ding to accommodate various volumes,-

expan such as a gas-holder or the like; 7

Oil is admitted to the carbureter prefer ably near the air-inlet andnear the bottom of the carbureter by a pipe Zi'rom any suitable externaloil-supply chamber 2. The form of oil-supply chamber which I prefer isthat illustrated in Fig. 9, in which the chamber 2 contains afloat 3,which controls an inlet 4 by avalve 5Q The float is guided by means of aspindle 6, provided with a screwed portion andnuts 9, whereby theposition of the float may be adjusted. The upper portion of thesupply-chamber 2 is connected by a pipe 10 with the carbureter, wherebyan effective equalization of the pressures is obtained. r H

There is preferably an oil-feed device for each section of'thecarbureter; but one common to all of the sections may be provided,if

desired, having'means for supplying each section from it. I I

The air is blown through one or more seetions-of the carbureter,becoming carbureted by its passage through the absorbent partitions, andleaves by the outlet 9, whence it passes-to agas-holder or the like;

In each of the air-supply pipes b h h is a 'valve or cock 1' '5 irespectively, controlled by the movements ofthe gas-holder or other Ipartof-the apparatus having movements in accordance, with thefluctuations of the demand. Slide-valves, such as those shown diaammatically in Fig. 5, may be used, or coc s, as shown in Fig. 7, thevalves or cocks {being so arranged that when the demand is sin all; theair is supplied to one section of the carbureter only-say to section0cth'e other sections it and 00 being closed. When the demand increases,however, and the bell falls,

another sectionsay xis added, and with a further increase in demand andconsequent drop of the bell the other section is put into operation.While the maximum demand exists all the sections are in operation, butas the demand decreases and the bell rises first the section 90 is putout of operation by the closure of its cook or valve '5 and then, i tthe bell rise enough, the cook or valve saaeee '17.. The valves or cocksmay be operated in any convenient manner from a guided rod carried andactuated by the gas-holder.

- Forproducing very large outputs of carbureted air I prefer to dividethe'carbureter into. elements each of which may consist of a Icarbureter divided into sections, as above de scr'ibed,"or may,.ifdesired, be self-containedthat is, it may consist of a carbureter, asshown inFig. 1, but without the partitions cl d, hsWiIlg onlyoneair-inlet and one gas-outlet. Thefcar'bureter elements may ln'orderto reduce'space be arranged one above another irf the form of a stack,as shown in Fig. 3', where aseries of carbureter elements are showmwhichare not divided into sections by partitiyins, each element having itsown inlet and outlet. All the air-inlets are, however,

branched from a common supply-pipe 11, and all the outlets dischargeinto a common upltake-pipe 12, leading to a gas-holder 13. T ecarbureted air is drawn from the gas-bell by a pipe 14. a

As in the carbureter arrangement described with reference to Figs. 1 and2, the air-supply pipes of'the elements may be controlled by anconvenient form of valve or cook actuate from the gas holder'or bell.The type of cock shown in Fig. 7 is preferable generally to a'slide-valve or series of slidevalves; but in some cases slide-valvesmaybe used. The ports in the bodies of these valves are of determinedsize, but the way through the plug of the valves which come into actionU before-the last one may be two or more times the size of the valvelastopened, according to the number of elements employed. The heads 30, F 8,of the valve-plugs may be made to fit a justably upon octagonal shanks(not shown) in order that they maybe laced in positions that will insureall the va ve-le- 'vers being in the same position, notwithstanding thefact that the ports of the various valve-plugs may be in differentpositionsi. e., some closed and some opened.

I have'found that the best manner of operating the valves or cocks fromthe gas-holder 13 is to provide the bell with a verticallyguided rod 21,Fig: 3, which engages with one slottedend 22 of a lever 18, mounted upona fulcrum 15. 'The. other end of the lever 18 is also slotted at 24 andcontains a block which is free to slide or play in the slot,. PivotallyIOO attached to the .block at 2 -is a"vertical rod 26, which isconnectedto the ends of the valve-levers 27 of the'various air-valves i,i i i of the carbureter elements in any convenient manner-for example,asshownin Figs6an d8. 4 v

I find in practice that it is important to be able to properly adjustthese valves in relation to the movement of the bell, the maximum amountof which movement is of course always constant. For this purpose I fixthe levers 27 of the air-valves in any man-- outlet-valves being nerwhich will allow of varying their effect ive lengths, such as that shownin Figs. 6.

creased by the amount 3 Fig. 6, the block will play in a different partof the slot 24, and although the angular movement of the lever 1' is notchanged the angular movement of the levers 27 and consequent opening-ofthe valves will be less. If the efl'ective lengths be decreased, then ofcourse the opening of the valves will be greater.

, When the bell is in the position shown-.- 11. e. with the bell in itslowest position-all the air-valves are open; but as it rises, due to areduction in the demand,'one or more of the valves are closed insuccessiongthe reverse action taking place when the bell falls again.-.In some cases, especially in large plant,it is desirable to providevalves inthe outletsof the sections or elements of the carbureter plant,as well as in the-inlets thereto, these perated a' similar manner to theinlet-valves,

a The carbureter is provided witha heatingjacket and with meansforcontrolling the supply of-heat thereto.

- When he carbureter is used for supplying carbureted air to aninternal-combustion en glue or the like, Iconduct the hotwater from theen inc-jacket into the heating jacket of the car ureter to supply theheat necessary for replacing that lost by vaporization.

find it orta'nt, however, to --fcontrol' the supply of. 7 eat to thecarburetor-jackets of the elements, for if on e of the elements be out,

of operation-and the sameamount of heat be still supplied oilwill be,vaporized therein, and

when that element is 'next put into operation an excessively rich gaswill for a short 'eriod flow into theholder. vide the hot-water-supplypipes 32,-Fig. 3,

of the various elements with valves or cocks 33, adapted to be operatedin a similar man ner' to the air valves or cocks above described and so"arranged that when a carbu reter element-is put out of ol'pe'ratiofi bythe closure of itsfair-valve the t-fiui supply ipe is also closed, Thisarrangement 15 illustrated diagrammatically inFig. 3; but it will beunderstood that it the levers of the A valves 33 a re to be operated bythe same ver-" tical rod as actuates the air-valve levers it isdesirable, though not necessary, to arrange the center of t e water-pipeat about the same distance fromthe vertical rod asthe vertical air-pipeis-t. e., in the positionshown by dotted lines W in Fig. 3. I

It will of course be understood mand only maintain constant theproportion of hydrocarbon per-unit volume of the carbureted air producedso long as no substantial changes in the temperature take place,

produced. To cohnteract fer to employ one or more thermostats, such :orvice versa if the temperature rise, valves may be placed at the outletsof one or.

To' prevent this, 'prothat the valves operated in accordance with thede-.

temperature is to alter the qililality of t e gas s eflect, I preas thatshown in Fig. 10, where a vessel is divided into two chambers 100 and101, separated by a partition 102, in which is a com.- municating hole103; Mercur is sup lied to the chambers, and in the chamber 10 is afloat 104, which supports a rod 105, assing through a tubular o'\ening106 in the )ottom ofthechamber an connected to an operat--ing-lever or the like of a valve. The thermostats are actuated bychanges of temperature of the atmosphere or by'a flame of the gasproduced, the thermostat" or thermostats being adapted to control one ormore valves 51 in the supply or supplies to or from the carbureters, asshownm F 1g: 3. Thus if the temperature falland-aweaker gas be producedin consequence the thermostat will.

open one or more valves wider and allow".

more rich carbureted air to pass into-the bell,

These more elements, or, as described in my former patent, N 0'.828,284, dated 'August 7, 1906, these valves may beplaced,concentrically within the other valves, or they may control f's'eparatecarburetor elements. The sup ly-pipe H of the'carbureter plant" 1is-provide with'an air-reliefvalve 40, adapt.

ed to beopened by the riseof the bell when'a j l s'ijdde'rr decrease inthe den." and takes .place.

valve is actuatedlby the movements of the gas-holder or other t eanshavin move nzents inaccordance with the dernan I prefer to make theinlet to the carbureter f and the. outlet therefrom in the form of aVenturi tube, as shown at 42 and 43 in'F-ig'. 3: I The pipe-deliveringcarbnret'ed airto the v bell is provided with a valve. '44, actuated.i'romthe movements of the-bellf This valve. .44 is'gradually opened orclosed as the'bell falls or rises, so that the admission "of mixtureinto the bell shall be controlled in ace cordance with the demand. I Thepressure of gas within the belliscon'stant', the movenients of thebellbeing in accordancewith the volume. At predetermined heights the bellentirely closes or-flly opens the-valve.

Although the volurre of air available for delivery into thecarbureter"'may; be i much greater than the demand-{for rr-ixttre, the

pressure in the bell is appreciably by this Va 1prevented from risingebell; v The gasfin the bell may be-used 1n some cases 'VVlhhiOlll)farther dilution; but when very dilute n' ixtrres arerequ ired I takerich gas from the bell of'the surface-controlled carbureter, mixitwithpureair, and pass the of dem andas, for instance, a bell- -theprovmixture to a second expansive receptacle having movements inresponse to. variations- 2 ve theinlet-pipe to portion of air to gasbeing automatically controlled bygneans operated in accordance with thedemand or thermostatically in accordance-With the temperature. -The'pipe conveying mixture to the second bell is con- I, trolled by a valvein accordance with the mo einentlof that bell, so as to keep thepressure therein constant, notwithstanding va-.

riations of demand. Means for efl'ecting this are shown diagrammaticallyin Figs. 11 and 12, in which the rich. carbureted air from the bell fthe stack-carbureter is conveyed by the pipe 14, and pure airis led bypipe 45 to a mixing-chamber 52, whence the mixture passes by a pipe 53into the second hell 54 and therefrom to the services by. a pipe 55. Inthe rich-gas pipe is a valve 60 and in the air-pipe a valve 7 O. In themixture-pipe 53 is a valve 56, operated Qbya rod 57, carried by the bell54, the rod engaging with one end of a lever- 58, attached to thevalvelug, the other end of the lever engaging avl ever 59,

J attached to 'the'valve- 60 inthe-rich-gas pipe 14; A lever 61,siirilar'to the lever. 58, (see Fig.12,) also operated by the moverrentsof .the bell,-engages a lever 62;.Fig. 12, fixed on the plugaof the-.airvalv e 7 O. The ports of the valves 60 and 70 are set so that whenone valve opensmore -or less the-other closes more or less." When theden and increases,

the bell sinks, therebyopening wider the mixture-valve 56, opening widerthe gasvalve 60, and reducing the opening of the airvalve 70, and viceversa, when the den: and

decreases. The proportion of hydrocarbon to air in the mixture, as wellas the pressure in the bell, are. thereby kept constant notwithstandingthevariations'of pressure. M To counteract the eifectrot variations ofthe temperature of the atmo's here within the carburetor, I providaan aditional valve in'fjone of the pipes 14 4 5, preferably'in the gas-pipe'14. I control this valve by any suitable thermostat GET-such, forexample,

j as that shown in .Fig. 10. The valve'l pref; erably placedconcentrically inside the plug of the valve 60, which may be madehollowto contain it, the ports or passage-Way's of, the two concentricvalvesbeing arranged so I that at noriral temperature and dent and both valvesare fully open but if the temperature-of the atmosphere rises "thethermostat partially closes the inner valve to let less gas pass intothe n'.ixing-chamhen-"the gas How ing through the valve being richer inconsequence of the increase of ten:perature.

A further check on the quality-of the nix-- ture may beobtained byproviding another valve -in, say, the air-pipe45, this valve beingcontrolled by a therlr ostat-64 in accord ance with the heat of a'flanteof. the gas pro duced. The valve may be concentrically arranged insidethe air-valve 70. The thermostat consists' of .a closed annular. chamberwhich the flame impinges, this chamber being connected by a pipe 66 witha small cylinder 67, in which is a lightly spring-pressed piston 68, themovements of which under the changes of pressure of the fluid in theannular chamber and pipe control the valve.

--Of course it will be readily understood that. the apparatus isapplicable for carbureting water-gas or the. like, the gas which it isdesired to enrich'be ing passed instead of air through the carbureter.

As abovestated, the means for automatically controlling the extent oramount of the carbureting-surface may be located both in the inlet-pipesto the carbureter or the'outlete leading therefrom, and in Fig. 11 Ishort the said automaticmeans located in the outlet-pipes as wellas inthe inlet-pipes, said automatic means consisting of the valves 50*,--51, 52, and 53. The stems of these valves are connected with a rod 64which connects through-a slot and a pin 62 63 with an arm 61*, formingan extension of face in accordance with the demand, it being noted thatthe connections described are operated by the rise and fall of the bell.
